BOTTLE FOR PREVENTING I REFILLING.

SPECIFICATION forming part of Letters Patent No. 700,070, dated May 13, 1902. Application filed October 1,1901. fierial No. 77,220- (No model.)

To all whom it may concern:

Be it known that we, JAMES FOSTER MC- CONAGHY and GEORGE GOODRIOK DUDDLES, subjects of the King of Great Britain and Ireland, residing at 19 Majoribank street, Wellington, in the county of Hutt, in the Pro-' vincial District of Wellington and Colony ofpart of this specification, Figure 1 represents.

a sectional elevation of the bottle. Fig. 2 shows a plan of the lower diaphragm situated in the bottle-neck. Fig. 3 is a plan of the intermediate diaphragm. Fig. 4 is a plan of the upper diaphragm.

Similar letters of reference indicate similar or corresponding parts where they occur in the several views. V

On referring to the drawings it will be seen that A is the body of a bottle, having above it the neck B. To below its junction with the body this neck is ground or opaque. It is therefore impossible to see the interior. At the bottom of the neck and inside the same is an intern ally-protruding annular seat 0, upon which is supported or rests the glass' or earthenware ball D. This ball, which may be ground, is of such a diameter as compared with its seat as to make a good contact therewith, the depth of the said seat or its bearing area being dependent. upon the diameter of the ball and of the neck of the bottle.

Above the top of the-ball and inside the" bottle-neck is an annular step or shoulder E. Above this thebottle-neck is larger in diameter than it is below. Upon this shoulder rests a glass orother diaphragm F. the lower? diaphragm and through it are perforations or incuts G, as" seen in plan in Fig. 2.

Above the lower diaphragm is the separating-piece H, (the lower.) This is superim- Zter'mediate diaphragm F.

Thisis called;

posed by andis preferably part of the intermediate diaphragm F, as shown in Fig. 3. Before being deposited in the bottle-neck care is takenthat the perforations G in the lower diaphragm are covered by the said in- Above the intermediate diaphragm and preferably part of the same is another separating-piece H, (the upper,) over which is the upper diaphragm F. This latter is also before deposition so turned that it covers the incuts or perforations in the intermediate diaphragm beneath it.

When the ball and the diaphragms are assembled in place, the bottle-neck is slightly heated and closed to the said diaphragms. They are thereby locked in position and prevented from removal unless violence is resorted to. This closing is easily and quickly performed withoutany great skill being necessary, and it can therefore be done by the bottler after the contents are in place in a few seconds with but a heater and closingtongs.

The lift of the ball will vary with its diameter, but in no case need it exceed one-quarter of the said diameter. As can be well understood, no wire, string, or other foreign substance can be inserted between the ball and its seat.

Though two diaphragms may efiectually bar any tampering with the ball, yet for safety sake three are preferred. The incuts may also vary in their number and contour and round perforations be used; but those illustrated are preferred.

Having now described our invention, what we claim as new, and desire to secure by Letters Patent, isr 1. In a bottleto prevent refilling a ball resting on an internally-protruding annular seat in the bottle-neck in combination with a guard secured in the,bottle-neck above the ball comprisingavlower incut or. perforated diaphragm, an intermediate incutor perforated diaphragm -.-hav ing above and below -it a separating-piece, and an upper diaphragm all as and for the purposes hereinbefore described and as illustrated in the drawings.

2. An improvement in bottles to prevent refilling consisting of a bottle having a body Ioci the neck of which is ground or frosted and all as and for the purposes hereinbefore do inside and near the bottom of which is an scribed, and as illustrated in the drawings.

annular protruding seat in combination with In witness whereof We have hereunto set our a ball resting on said seat, a guard secured hands to this specification in the presence of 5 in the bottle-neck, above the ball, comprising two witnesses.
